Vertical filtering

Description

The transformation allows users to select only a subset of the vertical domain for further processing. The filter is provided in the form of a range of layer indexes. The filter applies to gridded datasets and to meshes read as layers.

Example

This request to /api/conversion/upload-convert

{
  "readerName": "<reader name>",
  "writerName": "<writer name>",
    ...
  "transformations": [
    {
        type: "VerticalFilterTransformation",
        verticalFilter: {
            type: "VerticalIndexFilter",
            from: 1,
            to: 10
        }
    }
  ]
}

will select layers from 1 to 10 (0-based indexing).

Full 3D meshes

The vertical filter is ignored when a 3D DFSU file is read as full 3D elements (ReadFull3D = true on the DFSU reader). All layers of every column are imported, and the dataset keeps the original vertical domain (layer count and sigma layers) of the source file.

To import only a subset of layers, read the file as layers (ReadFull3D = false), or remove the layers from the file before the upload.
